More than 18 persons per one lakh people in Kolkata fall victim to lung cancer every year compared to the next highest 13 per one lakh in Delhi, according to environmental scientist and advisor of Chittaranjan National Cancer Institute (CNCI), Twisha Lahiri.
Not only lung cancer, cases of heart attack were also rising fast in the Eastern metropolis, Lahiri said quoting a six-year survey conducted by the cancer institute.
She said incidents of heart attack were occurring more frequently in the city.
CNCI scientists maintain that more than seven in 10 people here suffer from various kinds of respiratory disorder, including children as well as elderly people.
Lahiri said roadside hawkers, shopowners, traffic policemen, auto-rickshaw drivers, rickshaw-pullers and others who spend long hours on the road were the most vulnerable.
Children mainly suffer from breathing difficulties like asthma while elderly people are victims of lung cancer, the scientists said.
